In-Medium Mixing and the Phase Structure of QCD — •Fabian Rennecke¹, Lorenz von Smekal¹, and Maximilian Haensch² — ¹Justus-Liebig-Universität Giessen, Institut für Theoretische Physik — ²Ludwig-Maximilians-Universität München

Interactions in the hot and dense QCD medium give rise to extensive mixing between hadronic and gluonic degrees of freedom. This modifies the analytic structure of the systems and leads to a non-Hermitian mass matrix, with potential far-reaching consequences for the phase diagram. For example, regimes with spatial modulations and instabilities towards inhomogeneous phases can be induced by such a mixing.

Keywords: QCD phase diagram; inhomogeneous phases; mixing; Yang-Lee edge singularity
